Author's Note 

THE purpose of this work is to set out in alphabetical order 
some of die scientific, technological, and kindred inventions, 
discoveries and developments made since earliest times, indicating 
to whom each is attributable, together with the year in which 
they were made or introduced, if known. 

This knowledge has been gathered from many thousands of 
literary and factual sources, and represents the culmination of 
many years of intensive research, inquiry and travel. But a work 
of such coverage must, at very best, leave much to be desired. 
Any attempt to cover entirely the vast field of human endeavour 
down the ages must necessarily fall short of completeness. 

In this the serious student is invited to explore more fully the 
history of science, technology and engineering; but he must be 
prepared to accept that much early historical evidence still 
remains buried in original documents and periodicals in many 
languages. Here, then, is a wide-open field for his patient research 
and evaluation of the abundant material awaiting his efforts; 
and if this book helps him on his way, its purpose will have been
